Technical field
The present invention relates to the low-voltage electrical apparatus control element, relate in particular to a kind of control coil and application thereof of energy-saving alternating current contactor.
Background technology
It is to impose rated voltage at its control of product coil two ends that principle is cut-off in its control of CJ Series AC Contactor of present domestic use, produces magnetic force behind the coil electricity, with the armature adhesive, makes contact closure, the drive load operate as normal.But, pass to behind the alternating current its adhesive and keep power consumption all bigger because AC-control coil is one group of (or one) coil.
Summary of the invention
The object of the invention is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of coil module and application thereof of energy-saving alternating current contactor control to be provided.
The object of the invention can be realized through following technical scheme: a kind of control coil of energy-saving alternating current contactor; It is characterized in that; Comprise coil input end (A1A2), normally closed interlock (K1), diode (D5), pull-in winding, bridge rectifier, hold-in winding; Described diode (D5) is with after hold-in winding links to each other; Be connected in parallel on coil input end (A1A2) two ends, after described normally closed interlock (K1), bridge rectifier, the pull-in winding series connection, be connected in parallel on coil input end (A1A2) two ends.
A kind of application of control coil of energy-saving alternating current contactor is characterized in that, this application comprises:
(1) pass to ac rated voltage for contactor control loop coil input end (A1A2);
(2) to hold-in winding, another road to pull-in winding, makes pull-in winding and hold-in winding all obtain corresponding work voltage through normally closed interlock (K1) to bridge rectifier to alternating current through diode (D5);
(3) set up work magnetic field at pull-in winding and hold-in winding inside, under the force action of two coil magnetic field, promote moving armature and move to the static gag bit direction;
(4) elapsed time T, normally closed interlock (K1) separates, thereby cuts off the pull-in winding power supply, makes hold-in winding be in small operating current power supply and keeps long-term maintenance adhesive operating state.
Described time T is 30ms.
Described small operating current is that operating current is less than 20mA.
Compared with prior art, the present invention has the following advantages:
(1) contactor coil self power consumption when hold mode obviously reduces;
(2) circuit power factor obviously improves, and has reduced distribution transmission reactive loss, has optimized power grid quality;
(3) noise pollution obviously reduces, and creates the hommization operational environment.
Description of drawings
Fig. 1 is the circuit diagram of the control coil of a kind of energy-saving alternating current contactor of the present invention.
Embodiment
The present invention relates to the low-voltage electrical apparatus control element; Particularly a kind of energy-saving alternating current contactor; Be mainly used in and exchange 50HZ or 60HZ; Nominal insulation voltage be 660-1000V under the AC-3 use classes, the rated operational current when rated operational voltage is 380V is 9-400A, main supplies remote the connection and the usefulness of segment circuit.Be applicable to the control alternating current motor startup, stop and reversing.
Solved the energy-conservation and environmental issue of A.C. contactor.A new generation's energy-saving alternating current contactor (SXLC1) is an aim of creating conservation-minded society in line with country, the noise reduction energy-conserving product of on the basis of former CJX1 and CJX2 Series AC Contactor, developing.
This invention product is compared with former CJX1 and CJX2 series of products possesses following advantage:
(1) contactor coil self power consumption when hold mode obviously reduces;
(2) circuit power factor obviously improves, and has reduced distribution transmission reactive loss, has optimized power grid quality;
(3) noise pollution obviously reduces, and creates the hommization operational environment.
When giving contactor control loop coil input end (A1A2) when passing to ac rated voltage; (K1) special-purpose normally closed interlock to the bridge rectifier that alternating current is received product inner ad hoc meter to hold-in winding and another road through contactor through diode (D5) arrives pull-in winding; Make pull-in winding and hold-in winding all obtain corresponding work voltage; Thereby set up work magnetic field at pull-in winding actuating coil and hold-in winding inside; Under the force action of two coil magnetic field, promote moving armature and move to the static gag bit direction, through tens of milliseconds of times, (K1) of inner ad hoc meter separates on the special-purpose normally closed contact top of closing; Thereby cut off adhesive actuating coil power supply, make hold-in winding be in small operating current power supply (within the 20mA) and keep long-term maintenance adhesive operating state.
Because the hold-in winding design number of turn is a lot, internal resistance is very big, and operating current is very little, and to compare power consumption very little with the contactor control coil power consumption of general same specification current class of the same type.
Operation of this invention product (SXLC1 series energy-saving type contactor) is more safe and reliable, has overcome that direct current keeps in touch that device is answered electric network fault control power supply dead electricity and contactor can not discharge the deficiency of separation.Under power grid control dead electricity situation, the hold-in winding of this invention product (SXLC1 series energy-saving type contactor) in time dead electricity discharges, and withdraws from normal operation, breaks off control loop.This invention product keeps in touch device with similar direct current and compares thus, and product is more safe and reliable.
With SXLC1-400 is example, and per hour contrasting amount of electricity saving (kilowatt/hour) with like product CJX1-400 contactor coil power consumption separate unit is 0.0219 degree, and promptly continuous duty separate unit contrast every day amount of electricity saving every day is:
0.0219*24 hour=0.526/ * days
With 1,000 ten thousand/year calculating of this product of national demand, but every year, save electricity was:
0.526*10000000*360=18.936 hundred million degree
With 1.2 yuan of calculating of the every degree of commercial power, can practice thrift total amount and be: 22.723 hundred million yuan
18.936=22.723 hundred million yuan (RMB) of 1.2 yuan/degree of the electric * of hundred million degree
This Products Development is used all very big for the economy and society benefit of society thus.
